XML/XSLT为课程项目帮助

Question

我正在为我的介绍编程课做一个项目，我必须编写一个XML文档，该文档使用XSL文档在我的学校书店中显示书籍列表。

我已经完成了大部分内容，但是每当我尝试发布页面时，我都会在文档中遇到有关额外内容的错误。我不确定错误来自哪里。

这是我的XML文档：

这是我的XSL文档：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html> 
<body>
  <h2>Bookstore Inventory</h2>
  <table border="1">
    <tr bgcolor="#9acd32">
      <th style="text-align:left">BookTitle</th>
      <th style="text-align:left">Author</th>
      <th style="text-align:left">SellingPrice</th>
      <th style="text-align:left">PublicationYear</th>
      <th style="text-align:left">Publisher</th>
    </tr>
    <xsl:for-each select="bookstore/book">
    <tr>
      <td><xsl:value-of select="booktitle"/></td>
      <td><xsl:value-of select="author"/></td>
      <td><xsl:value-of select="sellingprice"/></td>
      <td><xsl:value-of select="publicationyear"/></td>
      <td><xsl:value-of select="publisher"/></td>
    </tr>
    </xsl:for-each>
  </table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>

我知道这是很多，我感谢任何帮助。

谢谢！

Answer 1

xml是案例敏感的：

<xsl:value-of select="booktitle"/>

将无法获得名为BookTitle的元素的值。除此之外，您的XSLT似乎还不错。但是您的输入不是。
